Automated Greenland Glacier Termini Position Time Series, Version 1
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/quemhttvxmrg
Description
This data set contains shapefiles of termini traces from 294 Greenland glaciers, derived using a deep learning algorithm (AutoTerm) applied to satellite imagery. The model functions as a pipeline, imputing publicly availably satellite imagery from Google Earth Engine (GEE) and outputting shapefiles of glacial termini positions for each image. Also available are supplementary data, including temporal coverage of termini traces, time series data of termini variations, and updated land, ocean, and ice masks derived from MEaSUREs Greenland Ice Mapping Project (GIMP) Land Ice and Ocean Classification Mask, Version 1 (nsidc.org/data/nsidc-0714/versions/1).
